Many of us have experienced the horrors of a bad workplace but what does a good workplace look like?

Jim Clifton, the chairman and chief executive officer of the Gallup poll organization, says he knows, based upon decades of polling data.

What follows, according to Clifton, are the 12 most important, and most predictive, workplace elements. If these elements are in place, the employer has an engaged, healthy workforce where employees innovate, work hard and achieve results. If these elements are not in place, it is likely that workers are disengaged, less healthy, less productive, and less invested in the success of the company.

In the last seven days, I received recognition or praise for doing good work.

My supervisor, or someone at work, seems to care about me as a person.

There is someone at work who encourages my development.

At work, my opinions seem to count.

The mission and purpose of my company makes me feel my job is important.

My associates are committed to doing quality work.

I have a best friend at work.

In the last six months, someone at work talked to me about my progress.

In the last year, I have had opportunities at work to learn and grow.

According to Clifton, a major reason that workforces are not engaged is bad management or what he calls “management from hell.”

Gallup research has found that the top 25% of employees — the best-managed — versus the bottom 25% in any workplace — the worst-managed — have nearly 50% fewer accidents and have 41% fewer quality defects. What’s more, he says, people in the top 25% versus the bottom 25% incur far less in healthcare costs.
